    摘要: A gear case seal is provided for use with a traction motor. The seal may have an arcuate body with an outer annular layer forming a centrally located channel extending along its length, and an inner annular layer bonded to the outer annular layer along opposing axial edges so as to close off the centrally located channel. The body may also have a middle layer disposed within the centrally located channel and made from a material different than a material of the inner and outer layers.

    摘要: An irrigation drip emitter, and methods relating to same, are provided for delivering irrigation water from a supply tube to an emitter outlet at a reduced and relatively constant flow rate. The emitter having at least one movable member for compensating for fluctuations in supply line fluid pressure. In one form the movable member includes a tapered baffle section movable between a first position wherein fluid is allowed to flow over the tapered baffle section and a second position wherein fluid is prevented from flowing over at least a portion of the tapered baffle section and the tapered baffle section effectively lengthening the extent of a pressure reduction passage. In another form, first and second movable members are provided for compensating for such pressure fluctuations. In another form, a plurality of inputs are provided which are movable between first and second positions to compensate for such pressure fluctuations.
